RUBBER TIRE SETTER.

EPECIFICATION formingpart of Letters Patent No. 662,651, dated November27, 1900.

Application filed February 26, 1900. $erial No. 6,437. (No model.)

To all whom it may concern:

Be it known that I, ALVARO S. KROTZ, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio,

have invented certain new and useful Improvements in Devices forEquipping Vehicle-Wheels with Rubber Tires, of which the following isspecification.

My invention relates to improvements in to devices for applying rubbertires to vehiclewheels; and it consists of a device for closing thespace between the ends of the rubber after the ends of theretaining-bands have been tightened or fastened.

In the drawings, Figure 1 is a plan View of my device, together with aportion of the rubber-tired wheel. Fig. 2 is a sectional view of therubber tire and clamp or pulling-bar. Figs. 3 and 4. are detail views ofthe device for gripping the rubber. Fig. 5 is a detail View showingmanner of removing the rubbergripping device from the tire.

Like parts are represented by similar letters of reference in theseveral views.

In the form of rubber tires largely in use for vehicles there areemployed as retaining devices bands of metal, which pass through therubber, and it is desirable in applying this rubber to the wheel toplace the rubber,

0 with the bands extending through them, within the channel-iron of therim of the wheel before fastening together the ends of theretaining-bands. A space is necessarily formed at the point where thebands are fastened for the purpose of having ready access to the wires,and though the rubber is compressed before being placed within thechannel the friction between the rubber and channel is such that it isnecessary to provide means for closing the space formed at said joint,and in the device described herein I have provided means for closingthis space.

In Fig. 1, Ct represents a bed or table upon which I mount the block b,with pins 29, b

and b projecting from its upper surface, any one of which may serve as afulcrum for the lever c, which is formed to fit over any one of saidpins. There is also mounted on this bed or table a block with a stop-pind, against which the Wheel d rests, and d is a clamp for clamping saidwheel in position. a represents a table upon which said wheel issupported. A link 9 connects one end of said lever c with one end of aclamp or pulling barf. Before the retaining-bands Z2 are fastenedL-shaped hooks e are placed under the tire, as shown in Figs. 1 and 2,one hook being placed back of the other. The extension 6 of eachL-shaped hook is placed under the tire, said extension engaging thebottom of said rubbertire, while the upper portion 6 engages with oneor" the clampsf on the clamp or pulling barf. The L-shaped hooks arebent near the middle of their main stem, forminga sloping shoulder c,practically conforming in shape to the upper part of the sides of thetire. This sloping shoulder assists in removing the hooks after the tireis in place, as shown in Fig. 5, and further permits of a narrowerconstruction of the pulling'bar, as shown in Fig. 6, making it lessexpensive and more easily operated. It can readily be seen that bydisengaging the upper portion 6 of the L-shaped hook from the clarnpfthe L-shaped hook can be forced from engagement with the tire, as shownin Fig. 5. When the lever c is operated, the clamp or pulling barfispulled along until the lever link and bar assume the position shown indotted line of Fig. 1, and for convenience the lever may be shifted toany pin on the block b which will permita greater or less movement ofsaid bar. After the ends h and b of the tire are drawn together theL-shaped hooks are removed by pulling the upper portion 01 the Lshapedhook toward the tire, thus prying the extension c from under the tire,the rubber tire itself serving as a fulcrum, as shown in Fig. 5. I havethus shown means by which the rubber will be drawn back against thefriction of the rub- 0 her and channel to a position which it willmaintain owing to the pressure of the rubher, and it is readily seenthat the pairs of L-shaped hooks act as sets of clamps, clamping therubber at the bottom and sides thereof, 5 but being readily removed inthe manner I have shown when the rubber has been drawn to the desiredposition.

For matter shown but not claimed refer ence is had to my applicationSerial No. 6,435.

Having thus described my invention, I claim as follows:

1. In a rubber-tire-pulling machine, the combination of L-shaped hooks,shaped to conform to the bottom and lower part of the sides of the tire,and bent near the middle of their main stem forming a sloping shoulderpractically conforming in slope with the upper part of the sides of thetire, said shoulders assisting to remove the hooks after the tire is inplace, and means for pulling said hooks for the purpose of closing therubber tire.

2. The tire-pulling device consisting of L- shaped hooks to engage thebottom and the lower part of the respective sides of said tire, saidhooks being bent near the middle of their main stem forming a slopingshoulder practieally conforming in shape to the upper part of the sidesof said tire, said sloping shoulder assisting to remove the books afterthe tire is in place and permitting the upper ends of said hooks onopposite sides of said tire being brought more closely to each other,and a pulling-bar clamp to clamp said hooks at their upper ends andmeans for pulling said pulling-bar clamp.

In testimony whereof I have hereunto set my hand this 13th day ofSeptember, A. D. 1899.

ALVARO S. KROTZ.
